Which scientist proposed that plants are made of cells?

• A. Virchow
• B. Schwann
• C. Hooke
• D. Schleiden

Answer: (D)

Plants are built from cells, and Matthias Schleiden showed this by studying a wide range of plant tissues and concluding that all parts of a plant are made of cells. This observation helped form the cell theory, the idea that cells are the basic units of life in living organisms. The concept was later extended to animals by Theodor Schwann, and Rudolf Virchow added that cells arise from preexisting cells. Hooke, meanwhile, is known for naming the cell after observing it in cork, but he didn’t articulate the plant-made-of-cells idea.
